  • Acid Base Titrations II: Potentiometric And Indicator T

    II: Potentiometric and Indicator Titrations Introduction- In this experiment, the reactions of three different acids with a strong base are studied by observing how the pH of the solution changes as the titrant is added. A plot of pH versus amount of titrant added will be constructed. Such a curve is called a pH titration curve. The equivalence point of the reaction will be determined from an analysis of the pH titration curve, and by the use of acid-base indicators. The pH measures the…

  • Calibration Of Ph Titration Essay

    Discussion Task 1. The calibration of pH meter was performed resulting a calibration equation Y=-57.833+403 (see appendix). After the calibration of pH meter the pH values show in the table 3, 6, 7, 10, 11 and 13 were calculated from the values of mv recorded by using aforementioned equation. Despite the values the pH reading were recorded the values used and reported in this experiment were the calculated pH. Task 2. The standardization of the titrant solution HCL was performed fallowed a…

  • The Bronsted-Lowry Theory

    equivalence is the point where the acids and bases have been added equally. The change from colorless to pink represents the end point of the reaction, indicating that the concentration of the acid can be measured. The point of equivalence will result at a pH of seven in the titration of sulfuric acid and hydrochloric acid with sodium hydroxide. Aim: The aim of the experiment is to find the unknown concentrations of the acids (Sulfuric and Hydrochloric) with the use of titration, using 50 cm3…

  • Natural Indicators Lab Report

    Natural Indicators Lab; a Study in pH Levels Using Green Cabbage Introduction- pH is the concentration of hydrogen in a substance. It is the scale used to tell how acidic or basic a solution is. The normal pH scale goes zero to fourteen. Zero to about six indicates that the solution is an acid. If the solution is closer to zero it makes it a stronger acid, but if the solution is closer to seven than it is a weak acid. If a solution has a pH of seven then it is neutral. A pH of eight to fourteen…

  • Feed Analysis Values

    detergent fibre, pH level and ash. Specifically, the value for the dry matter is the corrected value in order to allow for acids, volatile acids and other components that lost on oven drying. The crude protein which is determined from the total nitrogen of silage is 88.33 (g/kg DM). The value of the acid detergent fibre which is a measurement of lingin, cellulose and lignified nitrogen is 306.79 (g/kg DM). The neutral detergent fibre of the silage was 552.40(g/kg DM) and is an indicator of…

  • Acid Rain Research Paper

    Acid, below-normal pH, causes many problems in our world today—from drinks to teeth, from pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in…

  • Titration Essay

    identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items were used to help apply basic theories about acids and bases such as pH. The titration curves were evaluated to help determine which indicator needed to be used for the indicator titration. Anions are ions that…

  • Hydrochloric Acid

    both discarded into the waste bin and rinsed three times to prepare for the next trial. The same process was used to obtain the 50 mL of NaOH as in the previous experiment, but Ba(OH)2Ba(OH)2 was used instead. HCl was added to the phenolphthalein indicator and deionized water as in the first trial. 4 mL was added quickly and a singular drop was added slowly from there. A reaction took place at exactly 6 mL which was what was predicted. A light pink solution was produced. The second trial went…

  • Antacid Lab Report

    Antacids are a class of medicine which assist to balance the acidity/ pH balance in your stomach. The pH system is a scale which measures how acidic a substance is or how basic a substance is or if a substance is neutralized. Antacids have the ability to give relief for heartburn, indigestion or symptoms of acid reflux. There are many types of antacids such as calcium, aluminum and magnesium. They’re many ways to consume antacids such as liquids, tablets and chewable tablets. The experiment will…

  • Alkalinity Lab

    Alkalinity is a measure of the ability of a water to resist changes in pH. Alkalinity in water is due to the presence of weak acid systems that consume by hydrogen ion produced by other reactions, allowing chemical or biological activities to take place within a water without changing the pH (1). In this way the alkalinity protects aquatic life. The measured value may vary considerably with the end-point pH used. Alkalinity is a measure of an aggregate property of water and can be interpreted…
